Abstract Physical activity is important in human life at any age, but unfortunately, many injuries happen during times of practicing sports. Sports injuries account for about 16% of all recorded injuries in emergency departments in Sweden. Injuries are a major issue in most team sports; therefore, all sport teams work on having prevention of injuries. Handball is a tough sport with a lot of clash among the players that causes several injuries. The purpose of this study is to compare injuries between male and female handball players in the senior and junior teams, to see how much age and gender may affect the injury incidence. This thesis has studied handball injuries by choosing and examining random patterns from Swedish handball teams in various levels of senior and junior teams of both sexes. The Survey has been done in spring 2012, and I have personally designed the questionnaire. The study comprised of 226 players, including 128 seniors (53 women and 75 men) and 98 juniors (47 women and 51 men). The total number of the injured players was (145), and according to their responses of the survey, the total number of injuries was (220), meaning that 64% of the players were injured at least once during the season 2011-2012. Handball injuries are divided into two types: acute injuries and overloading injuries, and they can fall during training and matches. Finally, I conclude that there are no significant differences detected between the different groups of age and gender concerning injuries, locations of injuries, types of injuries (acute or overload), times of injury (trainings or matches) and periods of absence from trainings and matches, in Swedish teams of handball. However, the distribution of males are statistically different, p <0.05. That there are fewer injuries among seniors than juniors leading to absence 8-30 days from the times of matches and training, and more injuries among seniors leading to the absence>30days. Therefore, I which proves no differences between genders and ages in injuries.

Abstract This Paper has discovered a way to solve compilation problem of True time toolbox, a third-party tools inserts to Matlab for simulation purposes. Using the laboratory matrices language (Matlab) version 7.12, True time toolbox 2.0 Beta, a problem arises in the scientific laboratories of Dijlah University College, where it is noted that computers running under Windows XP with low requirement , within the normal installation of Matlab and visuals studio, shown to be ineffective due to the failure of compilation of files in the Matlab after added and tools file in the Windows, plus effecting stopping of Mikropic controller and shows some errors. Proven way proved scalability tools to work within high performance and all applications and programs in the exist windows.

Abstract -The research aims to identify the impact of using external feedback nutrition (verbal-visual) and their impact on the acquisition of learning some basic skills in tennis. The research hypothesis has been confirmed that there were statistically significant differences between pre and post tests for the two sets of control and experimental research in experimental research. The research sample included students of the second stage and the number (40) students. - the third section of the research included methodology and field procedures, where the researcher used the experimental method to achieve the research hypothesis. -the forth section has included the presentation of search results, analyzing and discussed them. - the fifth section included on the conclusions and recommendations reached by the researcher and the most important recommendations is the use of external feedback nutrition (visual-verbal) and their impact on the acquisition of learning some basic skills in tennis for beginners.
